Brian Foy aspirates malaria-causing mosquitoes inside a villager's home in Ibel, Senegal. Only female Anopheles mosquitoes transmit malaria; they pick up a parasite called a plasmodium from infected people when they bite to obtain blood needed to nurture their eggs.

Research assistant Alassane aspirates mosquitoes inside a villager's home. After feeding on humans during the night, the mosquitoes often hide in bedding and along ceiling rafters.

A trap at the end of electronic aspirator shows collected mosquitoes. According to the World Health Organization, there were about 627,000 deaths from malaria in 2012; 90% were in sub-Saharan Africa.

After collection in the trap of the electronic aspirator, the mosquitoes must be sucked out and transferred to specially prepared collection cups holding sugar water.

The verdant village of Ndebou, in southeastern Senegal. The warm climate of Senegal makes it an ideal breeding environment for mosquitoes, particularly in the wet season.

Villagers in Ndebou, Senegal, are part of a study on a parasite drug called ivermectin. The blood of villagers taking this medication seems to kill any mosquitoes that bite them.

Kevin Kobylinski adds sugar water to collected mosquitoes. The research team compared the life span of mosquitoes from Ibel, where villagers where taking ivermectin, to mosquitoes collected from Ndebou, where villagers where not on the medication.
